A method of manufacturing an undergarment includes moving a web of body panel material in a longitudinal machine direction and cutting the web of body panel material along the longitudinal machine direction to thereby form a rear body panel web and a front body panel web each having a maximum rise and a minimum rise respectively. The maximum rise of each of the rear and front body panel webs is greater than the minimum rise of a corresponding one of the rear and front body panel webs. The method further includes shifting at least one of the rear and front body panel webs in the longitudinal machine direction and thereby aligning the maximum rises of the rear and front body panel webs. The method further includes aligning a s crotch member with the maximum rises of the rear and front body panel webs and connecting the crotch member to the front and rear body panels. The crotch member includes at least one stretchable component including an elastic material. A disposable undergarment is also provided.

L'invention concerne un procédé de fabrication d'un sous-vêtement consistant à déplacer une bande d'une matière de plastron pour le corps dans le sens d'une machine longitudinal et à couper ladite bande le long du sens machine longitudinal afin de former une bande de plastron pour le corps arrière et une bande de plastron pour le corps avant, chacune ayant une élévation maximale et une élévation minimale. L'élévation maximale de chaque bande de plastron avant et arrière est supérieure à l'élévation minimale d'une des bandes avant et arrière correspondantes. Le procédé consiste en outre à déphaser au moins une des bandes avant et arrière dans le sens machine longitudinal, et à aligner, par conséquent, les élévations maximales des bandes avant et arrière. Le procédé consiste par ailleurs à aligner un élément d'entrejambe sur les élévations maximales des bandes avant et arrière et à relier ledit élément d'entrejambe aux plastrons avant et arrière. L'élément d'entrejambe comporte au moins un composant étirable renfermant en matière élastique. Fait également l'objet de cette invention un sous-vêtement jetable.
